Abstract: The present invention relates to metal complexes which contain elements of group IB and IVA mixed and electronic devices, in particular organic electroluminescent devices, which comprise metal complexes of this type. The compounds claimed are described by formula (1), formula (2) or formula (3), where the following applies to the symbols and indices used: M is on each occurrence, identically or differently, Cu, Ag or Au; E is on each occurrence, identically or differently, Si, Ge or Sn; the other variables are as defined in the claims.

Abstract: The invention describes electronic devices comprising a metal complex compound having at least one ligand containing an N donor and a P donor having the formula (I), in which the carbons C1 and C2 are part of an aromatic or non-aromatic ring system F1, P and N are phosphorus and nitrogen, where the nitrogen is in sp2-hybridized form, the radicals R3 and R4 are, independently of one another, hydrogen or an alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, alkylcycloalkyl, heteroalkyl, heterocycloalkyl, heteroalkylcycloalkyl, aryl, heteroaryl, aralkyl or heteroaralkyl radical having up to 40 C atoms, and R1 and R2 are, independently of one another, an atom or radical from the group comprising hydrogen, halogen, R, RO—, RS—, RCO—, RCOO—, RNH—, R2N—, RCONR— and —Si(R)X(OR)3-X, where R=an alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, alkylcycloalkyl, heteroalkyl, heterocycloalkyl, heteroalkylcycloalkyl, aryl, heteroaryl, aralkyl or heteroaralkyl radical having up to 40 C atoms and
